The new flexible and extensible modular solvers structure already provides most
of the simulation functionality needed for single phase, multiphase,
multicomponent etc. fluid flow problems as well as a very effective method of
combining these with solid heat transfer, solid stress, surface film to solve
complex multi-region, multi-physics problems and are now the primary mechanism
for the further development of OpenFOAM simulation capability in future. To
emphasis this for both users and developers the applications/solvers directory
has been separated into applications/modules containing all the solver modules:
├── modules
│ ├── compressibleMultiphaseVoF
│ ├── compressibleVoF
│ ├── film

│ └── XiFluid
applications/solvers containing the foamRun and foamMultiRun solver applications
which instantiate and execute the chosen solver modules and also standalone
solver applications for special initialisation and test activities:
├── solvers
│ ├── boundaryFoam
│ ├── chemFoam
│ ├── foamMultiRun
│ ├── foamRun
│ └── potentialFoam
and applications/legacy containing legacy solver applications which are not
currently being actively developed but the functionality of which will be merged
into the solver modules or form the basis of new solver modules as the need
arises:

Correspondingly the tutorials directory structure has been reorganised with the
modular solver directories at the top level with names that make it easier for
users to find example cases relating to their particular requirements and a
legacy sub-directory containing cases corresponding to the legacy solver
applications listed above:

In interFoam with momentumTransport simulationType set to twoPhaseTransport
separate stress models (laminar, non-Newtonian, LES or RAS) are instantiated for
each of the two phases allowing for different modeling for the phases.
This example case uses:
- phases "air" and "liquid"
- air phase
- constant/momentumTransport.air:
- stress model set to laminar, Newtonian
- constant/physicalProperties.air:
- transport set to const (Newtonian)
- mu (dynamic viscoity) = 1.84e-5
- liquid phase
- constant/momentumTransport.liquid:
- stress model set to laminar, Maxwell non-Newtonian
- nuM (kinematic viscosity) = 0.01476
- lambda = 0.018225
- constant/physicalProperties.liquid
- transport set to const (Newtonian)
- mu (dynamic viscoity) = 1.46
Liquid phase properties were calculated from the relations given in the paper:
- rho = 890 kg/m^3
- mu = mu_{s} + mu_{p} = 146 poise = 14.6 Pa.s
s = solvent (Newtonian), p = polymer (Maxwell)
- mu_{s}/mu_{p} = 1/9
=> mu_{s} = 14.6/10 = 1.46 Pa.s
=> nu_{p} = nuM = (9/10)*14.6/890 = 0.01476 m^2/s
